application filed April 29, 11926. fiellal lto. 103,20l.

The present invention is a closure for hottles andother containers, and the objects of the invention are to provide a cap of simple, inexpensive construction, capable of being easily applied and removed, and which at the same time forms an adequate closure for the container.

The cap disclosed herein is an improvement on the cap described and claimed in my copending application No. 693,849, filed Feb. 19, 19241:. The present invention provides means for reinforcing and stifiening the spring fingers so that the cap can be formed from relatively light-weightmetal.

In the drawings:

Fig. 1 is a plan view of a metal strip showing how the caps are punched therefrom.

Fig. 2 is a top plan view of the cap.

Fig. 3 is an elevation of the cap.

Fig. t is a bottom plan view of the cap.

Fig.5 is a cross section through the cap.

Fig. 6 is a cross section through a modified form.

Fig. l is a perspective view of the cap shown in section in Fig. 6.

Fig. 9 is a partial plan view, broken away and showing another modified form of the holding fingers.

Fig. 9 is an elevation of still another modification.

Fig. 19 is a section on line 19-10 of Fig. 9. The cap shown is stamped from suitable spring material, usually spring sheet metal, and is slitted atits periphery to provide the two sets of holding fingers l0 and 11. The fingers T0 are firstbentinwardly as shown in Fig. 3 and then the fingers 11 are bent into place. As a result of this procedure the fingers ll will overlap fingers 10, as indicated at 12 in Fig. 2. The width of the outer fingers 11 can be increased by swaging the edges of said fingers, thereby increasing the amount of overlap.

The spring holding fingers are turned inwardly to provide hooks or claws 13 (Fig. 3) to ride over and engage beneath a head or shoulder on the neck of the bottle or other container to which the cover may be applied.

lln order to reinforce the fingers so that the cap can be made from aluminum or other light-weight metal, the ends of the fingers are corrugated or crimped at 14.. Tn the modification shown in Figs. 6 and 7 the fingers are further strengthened by outwardly projecting corrugations or ribs 15 extending from the fiat crown into the bases of the fingers. The fiat crown may bereinforced by having an inwardly bulged central portion 16 or an inwardly projecting annular bead 17.

Tnthe modification shown in Fig. 8, the fingers ll are provided with lL-shaped extensions 18 which extend over the adjacent fingers l0 and into corresponding recesses 19. When removing the cap, the ends 20 of the extensions are forced out of engagement with the recesses, permitting expansion of the rim of the cap. The surface of the lower fingers 10 may be raised to the level of the upper fingers as at corrugations 22, to give the cap a relatively smooth feel.

In the embodiment shown in Figs. 9 and 19, the overlapping fingers are provided along the lower rim of thecap with outwardly bulging portions 24. These portions serve to strengthen the fingers and, furthermore, afford a secure finger hold for removing the cap. One of the overlapping fingers may be extended downwardly to present a lever 25, which by afi'ording increased leverage facilitates removal of the cap, the lever being first pulled away slightly from the wall of the container, and then pushed upwardly, when removing the cap.
